| Abstract: | Aiming at some problems that one pickup’s violent vibration and the greater noise etc.To build the multi-body dynamic model of powertrain mount system.The mounting’s stiffnesses are optimized by modal analysis,powertrain centre of mass acceleration and mounting response force simulations.Its vibration resistance performance is improved markedly.It is not only improve the comfortability,but also prolong the durability of engine and other components. |
